Find the two numbers whose sum is 27 and product is 182.
Let the first number be x
Let the second number be (27 − x)
✮ According to the question,
➾ x (27 - x) = 182
➾ 27x − x² = 182
➾ x² − 27x + 182 = 0
➾ x² − 13x − 14x + 182 = 0
➾ x (x − 13) − 14 (x−13) = 0
➾ (x − 14) (x − 13) = 0
Now,
➾ (x − 14) = 0 ⠀⠀and⠀⠀ ➾ (x − 13) = 0
➾ x = 14 ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀➾ x = 13
✮ Therefore,
→ If the first number is 14, then the second number is 13 and
→ If the first number is 13, then the second number is 14.
